求翻譯一段話---------英文,謝謝! 祝中秋快樂! As the wire diameter decreases from the nanometer to the angstrom (atomic) scale, the surface to volume ratio increases dramatically. In respect of the atomic wires with a diameter of only about one unit cell, almost all the atoms are on the surface, which will significantly enhance the photocatalytic activities. We will first develop chemical synthesis methods for the ultrathin non-metal-doped TiO2 1D nanomaterials, which emphasize the formation and controlled condensation of precursors. Secondly, we will elucidate the effects of size and doping of the ultrathin wires on their photocatalytic properties in the visible region of the electromagnetic radiation. Finally, to improve the stability and reusability of the photocatalysts, we will use silica mesoporous materials or nafion membranes as a support to disperse the ultrathin wire based photocatalysts. |

| 由于導線的直徑減小到埃(原子)的范圍,比表面積大幅增加。就原子導線而言,其直徑只有單位晶格大小,幾乎所有的原子都在表面,這將大幅提高其光催化活性。我們將首先開發(fā)超薄型非金屬摻雜TiO2的一維的納米材料,這種方法強調前體的形成和控制冷凝。第二,我們將闡明大小和摻雜對超薄導線的電磁輻射在可見光區(qū)域的光催化能力的影響。最后,為了提高穩(wěn)定性和光催化劑重復使用性,我們將用硅介孔材料或全氟磺酸膜作為支撐物,以分散立基于超薄導線的光催化劑。 |
